Doctors’ leaders say they “stand ready” to start providing a Covid-19 vaccine – with proposals being drawn up for clinics to run for seven days a week.
The British Medical Association said mass vaccination centres could be used “in a similar way to testing centres”.
It comes after early findings showed one vaccine in development could prevent more than 90% of people from suffering the effects of Covid-19.
A limited number of people may get that vaccine by the end of this year.
The developers, Pfizer and BioNTech, plan to apply for emergency approval to use the vaccine by the end of the month.
But it will not be released for use until it passes safety tests and gets the final go-ahead from the Medicines and Healthcare products Regulatory Agency.
The UK has ordered 40 million doses – enough to vaccinate up to 20 million people as each person will need two doses for it to work effectively.
Prime Minister Boris Johnson has warned people not to rely on the vaccine “as a solution” to the pandemic, saying it was “very, very early days”.
He said the development of a coronavirus vaccine had “cleared one significant hurdle but there are several more to go”.
The BMA said it expects “vaccine availability to be limited to begin with, meaning only small numbers of vaccine may be given in December and most vaccinations taking place in early 2021.
It said that, due to the logistics and delivery requirements, it was likely that groups of GP practices would need to work together with one “designated vaccination site”.
Dr Richard Vautrey, chairman of the BMA’s GP committee in England, said GPs and practice nurses have a “proven track record of mass immunisation campaigns” and were the right people to be leading the effort once a coronavirus vaccine becomes available.
